DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

iio: light: bh1780: fix PM runtime leak on error path

Move pm_runtime_put_autosuspend() before the error check to ensure the PM runtime reference count is always decremented after pm_runtime_get_sync(), regardless of whether the read operation succeeds or fails.

AnalysisAI

Local attackers with low-level privileges can trigger a denial of service in Linux kernel versions 4.7 through 7.0 by exploiting a power management reference leak in the bh1780 ambient light sensor driver. The vulnerability causes system resource exhaustion through improper PM runtime reference counting in the IIO subsystem's error handling path. Vendor patches are available across multiple stable kernel branches (5.10.253, 6.1.167, 6.6.130, 6.18.19, 6.19.9, 7.0), with EPSS probability of 0.02% indicating low observed exploitation likelihood and no active exploitation confirmed.
